大学英语作文:交流 Communication

Mobile phones are becoming increasingly popular nowadays, and the number of people using them has grown hugely, especially in developing countries. There is some debate about the safety of mobile phones, but in my opinion, the benefits from these phones are far greater than any possible health risks. There is some concern that mobile phones may cause brain damage or cancer because of the radiation they emit while they are being used. Some people are also worried that cell phone towers may be bad for health. However, researchers have conducted experiments over many years to find out if this is true, and so far they have found no evidence for this. On the other hand, mobile phones have many benefits, both for individuals and for isolated communities. They help individuals to communicate quickly and easily, and they can be used both for social reasons and in emergencies. For example, people can use them to contact their friends and, if they use texting, the phones are cheap and convenient. They are also very useful if someone has an accident while driving. In addition, isolated communities which do not have land lines can use mobile phones to contact the outside world, and this is much cheaper than installing land line phones. In conclusion, although some people are worried about the health risks of cell phones, there is little or no evidence for this. However, there is a lot of evidence for the benefits of cell phones, so in my opinion we should not worry about the dangers of cell phone use.

如今，手机正变得越来越普及，人们使用它们的数量已大幅增长，特别是在发展中国家。关于手机安全性的争论，但在我看来，这些手机的好处远远大于任何可能的健康风险。有人担心手机可能会导致脑损伤或癌症，因为他们在使用时会发出辐射。有些人还担心，手机塔可能对健康不利。然而，研究人员已经进行了多年的实验，找出这是真的，到目前为止，他们已经发现没有证据表明这一。另一方面，移动电话有许多好处，无论是对个人和孤立的社区。他们帮助个人快速和容易沟通，他们可以用于社会原因和紧急情况。例如，人们可以使用他们联系他们的朋友，如果他们使用短信，手机是便宜和方便。他们也非常有用，如果有人在驾驶时发生意外。此外，隔离的社区没有土地线，可以使用移动电话与外界联系，这是非常便宜的，比安装陆地电话。总之，虽然有些人担心手机的健康风险，但很少有证据证明这一点。然而，有很多的证据，手机的好处，所以在我看来，我们不应该担心手机使用的危险。
